If you’re a fan of the TV series, The Big Bang Theory you're probably used to laughing at Penny and Sheldon's interactions, especially when Dr. Cooper tries to explain physics to his loveable blonde neighbor.
One such instance is captured in the picture below. If you look at it, you could easily imagine Sheldon saying something like: “See, Penny, this equation accounts for the branching ratio of a top quark decaying into a W boson and bottom quark, as depicted by the upper-left diagram.”

Do you think Sheldon took up drawing simply so he could flirt with Penny?
